Network Hardware

Networks are made up of both hardware and software. The network hardware provides the physical connections between the network’s various nodes and typically includes:

Network Interface Cards (NICs), one for each PC

Network devices such as hubs, bridges, routers and switches, that are together responsible for connecting the various segments of a network and for ensuring that packets of information are sent to the intended destination

Network cables (sheathed copper wiring like telephone cords) which connect each NIC to the hub or switch.
